USB 5 V DC charging cable for 2.5 mm devices

This two-pack supplies a USB-to-2.5 mm round DC cord that fits massagers, toys and other hardware using a 2.5 mm charging port. Each cable measures 2.7 ft (82 cm) overall with a DC head length of 0.7 inch (18 mm) and a head diameter of 0.1 inch (2.5 mm). The pure copper core is intended to improve durability and safety during regular charging.

Pure copper core and dual-cable bundle

The copper conductor replaces thinner alloy wires found on some replacement cords, reducing voltage drop and heat build-up. Having two identical cables in one pack lets users keep one at a desk and another in a travel bag without buying a second package.

Buyers needing a 2.5 mm DC connection from any USB

The cable works with wall chargers, power banks, laptops, PCs and car chargers that deliver 5 V over USB-A. It will not suit devices that require a larger barrel jack, a proprietary magnetic tip or a higher voltage than 5 V. Users who need a right-angle plug or a longer run should look elsewhere.

Questions about this item

How often should I check the 2.5 mm DC plug for wear?

Inspect the 0.1 inch diameter tip every few months; replace the cable if the connector feels loose or shows bent pins.

What length limit affects charging speed on a long run?

The 2.7 ft cable keeps voltage drop low for 5 V USB sources; longer runs would increase resistance.

Does the pure copper core get warm during all-day charging?

The copper conductors stay cool at typical 5 V loads; only the USB power source may warm up.
